The warning “Check fuel fill inlet” in your Ford Fusion means that the capless fuel system is probably quite full of mud and dust and it needs proper cleaning. The best thing to do is to clean it with a good cleaner and lubricate at the same time. You may use Sea Foam for this, or you may also use WD-40 or other liquid lubricants that you can spray directly onto the flap.
After you clean the flap on the outside, you should spray a bit of cleaner on the flap and then use the gas station nozzle or the manufacturer-equipped funnel to open and close the flap several times. This will allow the flap to clean and lubricate the needed parts.
Fortunately, this problem may easily be solved without any professional help.
